Energia for FRAM and other new MSP430 Devices?

Recommended Posts

Hi All,

 

Would there be sufficient interest in some of the new FRAM parts to warrant an update of Energia to support these?

 

The $16 MSP430FR5994 LaunchPad is remarkable value, and an ideal platform for datalogger/low power sensor applications with 256Kbytes of FRAM, a microSD card, and 68 lines of I/O.

 

The MSP430FR2433 is also a neat little part, and if you need 4 x 24bit ADCs for instrumentation or energy monitoring the MSP430i2041 is one of the cheapest solutions for independent 24 bit ADCs around.

 

I would be interested to know if there is a plan for Energia to support these recently released new parts?

Hi @@monsonite

 

There are already a lot of LaunchPads being maintained by the Energia team and I imagine they have to manage their resources.  Maybe the @enegia will comment on plans.

 

I recently bought a MSP430FR5994 LaunchPad and really like it for the reasons you have outlined above.   I think it would be a good addition and had a look at porting it - should not be too difficult.  If there is interest, and there are no near term plans for official addition to Energia, then I am willing to give it a go.  I have ported a couple of the G series successfully.  The problem with these individual efforts is that resources are also limited and I for one am not willing to commit to long term maintenance.  Much better if the Energia team is willing and able to do it....

 

Regarding specialized ADC, another way to do it is to treat it as a serial sensor and read it using Energia from a LaunchPad.  Use the CCS examples to read ADC and for serial communication.

The problem with Energia right now is that it is using msp430-gcc. There are plans to move to the RedHat/TI port of msp430-elf-gcc soon but there are issues. Until then you can't use all the FRAM just the FRAM in the first 64k address space, which is typically about 48000 bytes instead of all the fram available at 0x10000 and above.

It may be worth waiting for the next release of Energia to see if that is addressed.  It appears there are other changes, such as the IDE, that will occur as well.
